Abstract
A temperature-type expansion valveincludes a valve housinghaving a first passageinto which a high pressure refrigerant flows, a second passagethrough which a low pressure refrigerant flowing to an evaporatorflows, and a throttle passagecommunicating the first passagewith the second passage; a valve bodyhaving a valve membervarying a sectional area of the throttle passage; and an operation rodfor driving the valve bodyin the interlocking arrangement with a displacement memberundergoing displacement in accordance with a pressure difference between a saturation pressure corresponding to an outlet temperature of the refrigerant of the evaporatorand an evaporation pressure of the evaporator; wherein a slide holecommunicating with the throttle passageand accommodating the valve bodyis formed in the valve housing; and the valve membermoves inside the slide holein the interlocking arrangement with the operation rodto thereby adjust the sectional area of the throttle passage. Construction can be simplified and the number of components can be decreased.
